Practically every Pole has at least one Jewish ancestor
Never in my life have I heard more outrages claim than this one. You don’t even believe it yourself.
People in the past rarely married outside their religious circles and it was very unusual for a Pole to convert to Judaism.
during inter-war Poland marriages between Poles and Jews became more common.
Poland’s inter-war Jewish population was about 3.3 million out of 33 million or roughly 10%. As you have said yourself such marriages were just more common during inter-war period lasting only 20 years. Even if all Jews married outside of their own this would still be impossible to achieve, not to mention the fact how Nazis viewed the offspring of such union. Are you telling us that the Holocaust is just a myth? For every Pole to have at least one Jewish ancestor to be even partly true all the Jews of Poland and their offspring of mixed marriages would have to survive, only Poles would have to die during the war. I never ever heard a more twisted logic than this one. How desperate do you have to be to make such a claim?
although it was unusual for a catholic to become a Jew it wasn't as unheard of for a Jew to become a catholic. That's why there's a higher chance for Poles to have Jewish ancestors than for Jews to have Polish ancestors.
That’s not true now is it? Almost every Jew on this forum had argued that Jews are neither a race nor ethnic group, its simply religion. Therefore once you change your religion you’re no longer a Jew. There simply can’t be any Poles out there with Jewish ancestors. However on the other hand; you are only acknowledged and accepted as a Jew by the rest of Jewish community if your mother is a Jew. They are the keepers of the faith therefore no matter who the father might have been her child is a Jew. If the father of such child happens to be Polish and being Polish is recognized as belonging to some sort of ethnic group, a child of such an union is a Jew of Polish ancestor. That's why according to your own logic argued by many Jews on this forum there can never be any Poles of Jewish ancestry but there are plenty of Jews out there with Polish blood in them.
Twisted as it may be it’s an accurate assessment of what many Jews have argued on this very forum unless they only hold it to be true when it suits them.
